Answer:

Three-fourths × 56

0.75 × 56

3 × 14

Step-by-step explanation:

To obtain 75% of 56 ;

Mathematically ;

75% of 56 = 75/100 * 56 = 42 (valid)

= 0.75 * 56 ( valid)

(75/100) * 56 = (3/4) * 56 = 42 (valid)

(75/100) * 56 = (3/4) * 56 = 3 * (56/4) = 3 * 14 = 42 (valid)

0.25 * 56 = 14 ( invalid)

(1/4) * 56 = 14 (invalid

Step-by-step explanation:

From the question, we are informed that a coach has 17 pompoms to give to her cheerleading team and that each cheerleader needs 2 pompoms to compete.

The greatest number of cheerleaders that can compete will be calculated as:

= 17 / 2

= 8 1/2

Therefore, the greatest number of cheerleader is 8.

There be 1 pompom remaining.

Answer:

A = 60 degrees

C = 8 m

Step-by-step explanation:

Whenever we are faced with a geometry problem, and we have a right-angled triangle within the problem, we are to remember Pythagoras' Law first, and the fact that a right-angled triangle always has an angle that measures 90 degrees.

We will also need to know that the sum of the angles in a triangle is 180 degrees.

Therefore, angle A will be = 180 - (90 +30) = 60 degrees

From Pythagoras' Law, we can see that [tex]c= tan 30 \times 8\sqrt{3} =8[/tex]

therefore, line c = 8m

Answer:

I will explain each step

3(x-y) / 2 =9

so first you have to make the equation equal to 0 so you can find the intercepts

3(x-y) /2  -9 =0

now simplify

3x-3y/2 -9 =0

2(3x-3y/2 -9)=0(2)

3x-3y-18

we will factor

3(x-y-6)

3=0

(x-y-6)=0

make the x=0 to find y and vise versa

(-y-6)=0

-y=6

y=6/-1 or -6

(x-6)=0

x=6/1 or 6

2/3x +4(y-2)=0

it is already equal to 0 to we simplify and factor

3(2/3x = 4(y-2)= 0(3)

2x+ 4y -8

2(x+y-4)

2=0

as we did in the last problem make x=0 then do the same to y

(y-4)=0

y=4

(x-4)=0

x=4

Answer:

x<=12

Step-by-step explanation:

3x+(-4)<=2x+8

3x-4<=2x+8

3x-2x-4<=8

x-4<=8

x<=8+4

x<=12

Answer:

12 ≤ x

Step-by-step explanation:

3x-4 ≥ 2x+8

3x-3x-4 ≥ 2x-3x+8

-4-8 ≥ -1x+8-8

-12 ≥ -1x

You divide -1 on both sides and get...

12 ≤ x

Because you have to switch the sign around. I hope this helps!!

Answer: $70.49

Step-by-step explanation:

Cost of gasoline = $2.75 per gallon

Cost of diesel fuel = $3.02 per gallon.

Since Gabriel needs to purchase 15.2 gallons of gasoline for his truck, the amount spent on gasoline will be:

= 15.2 × $2.75

= $41.80

Since he needs to spend 9.5 gallons of diesel fuel for his tractor, the amount spent on diesel fuel will be:

= 9.5 × $3.02

= $28.69

Total cost spent will be:

= $41.80 + $28.69

= $70.49

Answer:

CD = -2x

Step-by-step explanation:

Negative reciprocal

Answer:

D. twenty-eight and nine tenths

Answer:

First, let's define the transformations in a general way.

Vertical translation:

A vertical translation of N units is defined as:

g(x) = f(x) + N

if N is positive, the translation is up

if N is negative, the translation is down.

Horizontal translation:

A horizontal translation of N units can be written as:

g(x) = f(x - N)

if N is positive, the translation is to the right

if N is negative, the translation is to the left.

Reflected vertically (or a reflection over the x-axis)

This type of reflection changes the sign of the y component.

We can write those as:

g(x) = -f(x)

Then:

We start with the function:

f(x) = 2^x

First we reflect it vertically.

g(x) = -2^x

now we do a vertical translation of 5 units up, then:

g(x) = -2^x + 5

Now we do a translation of 3 units to the left, then we get:

g(x) = - 2^(x + 3) + 5

Then we already did the first step.

Now we want to find the domain for this function, the domain will be the set of the possible values of x that we can input in the function g(x).

Notice that in this function the denominator is never zero, so there are no values of x that generate problems here, so the domain will be the set of all real numbers, that can be written as:

(-∞, ∞)

3) Now we want to find the range, this is the set of the possible values of g(x).

The Largest value of g(x) will be when the exponential part tends to zero, this is for really small values of x, such that when x goes to minus infinity, -2^(x + 3) goes to zero.

Then:

g(-∞) ≈ 5

The maximum of the range is 5.

And we do not have a minimum, because as x increases the function will decrease infinitely.

Then the range will be:

(-∞, 5)

(A graph of the function can be seen below)

Step-by-step explanation:

Step-by-step explanation:

Kinetic Energy (K. E) = 25 J

Mass ( m) = 2 kg

Velocity or speed (v) = ?

We have the formula that

[tex]ke \: = \frac{1}{2} m {v}^{2} \\ or \: 25 = \frac{1}{2} \times 2 \times {v}^{2} \\ or \: 25 = {v}^{2} \\ or \: {5}^{2} = {v}^{2} \\ therefore \: v \: = 5 \: m |s[/tex]

it's speed is 5 m/s .

Hope it helps. :)

The speed of the body is 5 m/s

Applying the formular of kinetic energy

Kinetic energy: This can be defined as the energy posses by a moving body or that depends on the speed of a body.

The formular for kinetic energy is

E = mv²/2.................... Equation 1

Where E = Kinetic energy of the body, m = mass of the body, v = veocity/ speed of the body.

make v the subject of equation 1 above

v = [tex]\sqrt{2E/m}[/tex]................ Equation 2

From the question,

Given: E = 25 J, m = 2 kg

Substitute these values into equation 2

v = [tex]\sqrt{2*25/2}[/tex]

v = [tex]\sqrt{50/2}[/tex]

v = [tex]\sqrt{25}[/tex]

v = 5 m/s.

Thus, the speed of the body is 5 m/s

Answer:

5b - 3

Step-by-step explanation:

5b-3 is the algebraic expression for "3 less than the product of 5 and b"

Expression is a combination of variables, numbers and Operators.

The given sentence is

"3 less than the product of 5 and b"

Let us write the sentence in algebraic form.

We know that product of 5 and b means multiplication of 5 and b that means five times of b.

3 less than means subtracting 3 from another number.

So 3 less than the product of 5 and b is 5b-3.

Hence 5b-3 is the algebraic expression for "3 less than the product of 5 and b"
